UNITED-STATES This invention relates to glare controlling attachments especially adapted for use on the headlights of automobiles,` locomotives and the like.

5 Briefly stated, an important object of this invention is to provide a glare controlling means for headlights which may be attached to a conventional headlightl without any alteration whatever and which may therefore bl'lipplied without theexerciseof unusual Another important object of `theinvention is to provide a headlight attachment of the character specified which is ot highly simplifiedl construction, convenient to operate, and cheap to manufacture.

Other objects and advantages will be apparent during the course of fthe following description.

Figure 2 illustrates the usual socket mein her 7 which as is well known isadapted to receive the base 8 ot' an incandescent bulb.

9, the base being provided with lugs i() which engage in slots in the socket ineni- I ber whereby to hold the bulb firmly in place.4 As previously stated, the invention torin-` r,out the employmentof separatefastening ingthe subject matter of thislapplication 1s essentially in the nature of ari?attach .ment for a conventionallheadlight and 'it consists of a frame havin diver g arma 12arranged at opposite si es of t e bulb 9 .5 and connected at the rear ends thereofto an attaching ring 14, the rin 14 ,being adapted to be connected in t e manner shown in Figure l2. It is thus seen that the attachment may bef employed withli changing the vstyle of thelbulb9fo'r with devices and what is `more"important with out altering the design or Sham of thetlp tric bulb or headlight. l `1II` The forward portions of the divergixi ai-nis 12 have connection with an annulus 16 `to which a shutter' 18 is horizontally k hinged as indicated at 19. More specifically the lower portion of the annulus `16 is pro- 7i vided with a pairwof apertured'ears` 20" between which a hingelbarrel or earlhf the .shutter is positioned and these parts horizontal supporting bracket 26 extended forwardly' from'the lower portion of the annulus 16. The -bracket 26 may. be magj netized if desired so as to prevent uncon- II 'trolled movement of the shutter when open.

The shutter 18 may `consist of` a rirn havi ing a lens 27 ofzsomeitransparent or trans#` lucent material. If desired the shutter :frayV l be ot` solid metal or it may be of glasshav-/M ing prisms designed to throw the light"` downward. In fact the shutter 18ma `be of any material or form capable of del ecting .tlie objectionable light rays when the shutter 1, `isin its elevated position in front ofthe MiiV light bulb. W' ,Figures 1, 2 a `at)ii`iag ;n`et3() is positioned at one side of .the annulus 16 and `is secured thereto by a .n .si rap lll. '.Ihe strap may be Welded or othei l3 clearly illustrate that y wise secured to the annulus `16. The macneti "i 2i() has connection with electric wiresw uch may extend from a remote point. 0f course the electric 'wires have yconnection with afi* source of 4energy such as a battery `and :i105

switch may be located at any place within "l convei'iient reach of the operator. For eX- ninple the switch may be located on the steering column, thesteerini,r wheel, or the dash of the motor vehicle if, indeed, the

invention is employed on a moto.' vehicle. However, 1t is to be. remembered, that the niventioniis not in any way restricted in 'its application to an automobile vas it is 6 equally adaptable to the headlight of a locomotive or r the like. "'hcn vthe magnet H0 is venergii/.ed theI lug 36 lon the, shutter '1S will he attracted so that the shutter will promptly move to closed position directly 10 in front of the light bulb. This ot course obscures the objectionable light rays which emanate from the, central portion of the headlight. However, the movement of the shutter to a position directly in liront ot` `17H5 the light bulb does not in any way interfere ywith the light rays reflected from the outer portion of the paral'iolical reflector and therefore an annular beam ot light will go forwardv from the lain i. This annular beain Si 'oflight will be sufficient to illuminate the roadway a reasonable distance in advance of theI automobile, but. will not be objectionable' to the ,drivers ot approaching vehicles. 5 Iny the vforni of invention illustrated in `"f1 2t?y Figures 4 and 5 the traine is provided with `the tubnlarattaching portion l0 having the forwardly directed diverging arms tl to 'i which the annulus 42 1s connected. ligure Af 5 clearly illustrates that a pair ot semi-circular shutters 43 are horizontally pivoted rod 46 is positioned below and in the field `vof magnetic force oi" a magnet t9 and when i `the magnet is energized from a remote point. the rod is lifted to hohl the shutters in open position and thereby perniitot the uninterrupted' passage of the light rays. ln this 'foi'iii'ot' the invention the' magnet 49 must continue to be energized to retain the rod ,'46 in elevated position. When it is desired to ohseiire'the light emanating directly from the bulb the. supply of current to the inag- 'inet 4l) maybe cut ott` to allo'w -the weight 'of the rod 46 to move the lshutters #lil to lclosed and overlapping position as .shown in Figure 4.' lt is believed to be obviousl that the shutters will remain in this position funtil the magnet. is again energized.

' "lVhen the shutters are in their closed positions, as shown in Figure 4. the direct light rays are interrupted, but light beams ina; go forwardly" from the relier-tor, but. wil be insiitlicici'it to cause. annoyance to the,

y drivers of. ap'p'roinfhing vehicles.

il In the l'orinof invention shownin A'Figures 6fiind`7'the shutter support is in the t'orin yeu00"'of an anniilus 50 having the arms Til which converge toward an attaching member b v means of which the device may. be, quickly "secured to 'a conventional headlight with- *outfany i'ii'oditication whatever.

circular shutters 53 are vertically pivoted between their opposite edges thereot' as indicated at 54 and are connected by means ot' a magnet responsive rod or link 56- arranged horizontally aS shown in Figure 6. .lhe edges ot' the vertically pivoted shutters 525 are provided with the loops to which the magnet responsive element 5G is connectcd.

ln carrying out this torni ot' invention two magnets (it) and Gt are arranged at opposite sides of the t'rame 50 and when separately energized will draw the rod 56 in the proper direction. that is to say, when the magnet 61 is energized the shutters will he, moved to closed position as shown in Figure G. 0n the other hand when the magnet Gt) is energized the .shutters 53 are moved to the Open position as shown in Figure if It is helieved to be obvious that the magnets and (it are not operated at the same time, but operated separately to either cloae or open the shutters. The magnets G0 and 61 have connection with a suitahlesource of electrical energy and a switch oi" any type may be employed in the circuit so that the operator may at will interrupt the light rays emanating directly from the light. bulb in advance ot which the shutters are located.

ln the term of invention illustrated in Figures` S and 9, the shutter supporting ring or aniinlns Tt) is provided with thi` arms '71 to which an attaching collar or member is connected whereby the ring may be mounted slightly in advance of a light bulb without in any nay changing the construction of the associated headlight. rl`his forni ot' the invention is especially adapted t'or interruptingI only a portion of the light rays k'which emanate directlv i'roni the light bulb and by reference to Iiigure t* it will bc seen that the single shutter 'i5 which is of scnii circular formation is vertically hinged to the annulus T0 :isI shown .1t it. "l'hc semicircular'slinlter T5 is: proilcd adjacent the lower portion thereof with a lng or ear T8 in thc tield oi' magnetic influence ol' a magnet St). the magnet. being secured to the unnulus 'ill by a bracket B2i. Of course the magnet U has electrical connection with ii source ot' current and as stated in connection with the other forms ot' invention a switch may be placed at a suitable point in the circuit. ()t` course thc shutter may be two-thirds or any other part o f a complete circle without departing from theviiivention.

rl`he forni of invention shown in Figures S and t) will interrupt only those rays which are objectionable to the drivers of approaching automobiles and will allow light rays to go forwardly directly from the light hiilb and illuminate the side. oF the roadway opposite the drivers ot approaching vehicles. lt will therefore he .seen that the attachment In 'this forni of invention Athe semishown in Figures t5 and t) may he advantamamie geously employed for avoiding objectionable light rays and at the saine time allowing theright handsidemozt the road directly in advance of the automobile to befully illuminated.

The invention which isessentially in the `nature ofian attachment may be applied to 4the lantern, the socket member or the bnlb.

. such minor changes in arrangement and construction of parte may be made as will re- 'iiiain within the spirit ot the invention and' the scope of What-is claimed.
